Dental treatment with heart disease or high blood pressure

If you have a heart condition or take blood pressure or heart medication, dental appointments can feel daunting. The good news is that for most people with managed cardiac conditions, routine dental treatment is straightforward and safe. The key is making sure your dentist has the right information before treatment starts.

What to tell your dentist before treatment

• Your exact cardiac diagnosis (heart failure, valve disease, pacemaker, stent, bypass, arrhythmia, etc.)
• Every medication you take, including aspirin, blood thinners, beta-blockers, and ACE inhibitors
• Your current INR if you take warfarin
• Your cardiologist's name and contact details
• Any recent changes to your medications or condition

Dental treatment does not have to be deferred because of a heart condition, but your dentist needs this information to plan safely. Some procedures may be timed around medication doses, or a brief check with your cardiologist may be arranged first.

Blood pressure and dental treatment

Dental treatment is generally safe with well-controlled hypertension. If your blood pressure is very high on the day, the dentist may defer non-urgent work and recommend you see your doctor first. Local anaesthetic agents used in dental work contain a small amount of adrenaline (epinephrine), which most patients tolerate well; for those with severe or poorly controlled hypertension, the dentist can use a formulation without it. Anxiety itself raises blood pressure, so letting the dentist know you are nervous helps; our post on dental anxiety has practical advice for nervous patients.

Blood thinners

This is one of the most common concerns. The general guidance from cardiac and dental organisations is that blood thinners should usually be continued for dental treatment, including most extractions. The risk of a cardiac event from stopping anticoagulation typically outweighs the risk of bleeding from a dental procedure. Your dentist will use local measures (sutures, haemostatic agents) to manage any bleeding. Always check with the prescribing doctor if you are unsure; do not stop medication without medical advice.

Gum disease and the heart connection

Research consistently links severe gum disease to elevated cardiovascular risk. Bacteria from periodontitis can enter the bloodstream and contribute to arterial inflammation. For heart patients in particular, keeping up with regular professional cleans and treating any gum disease promptly is not just about oral health. Our guide to how oral health affects overall health covers the evidence on this link.
